JOHN RAPHAEL ROGERS, OF BROOKLYN,'NEW YORK, ASSIGNOR TO MERGENTHALERLINOTYPE COMPANY, A CORPORATION OF NEW YORK.

LINOTYPE-IVIACHINE.

T0 all whom it may concern.-

Be it known that I, JOHN RAPHAEL Roo- ERS, of the borough of Brooklyn,county of Kings, and State of New York, have invented a new and usefulImprovement in Linotype-Machines, of which the following is aspecification.

Myinvention has reference to a matrixdistributing mechanism of thecharacter represented in commercial Mergenthaler linotype-machines ofthe present day and represented in its general organization in LettersPatent of the United States Nos. 347,629 and 436,532. In this mechanisma stationary horizontal bar of V form at the lower ed e is provided withshort longitudinal teeth, varying in number and arran ement at differentpoints in the length of t e bar, for the purpose of giving support tothe matrices, which have their upper ends notched and provided withteeth to engage those on the bar, the arrangement being such that eachmatrix is held in suspension as it is carried along the bar until itarrives over its proper channel in the magazine, whereupon its teeth thefirst time bear such relation to those on the bar that it is releasedand permitted to fall therefrom. The movement of the matrices along thebar is effected by parallel screws, the threads of which engage theedges of the matrices.

In practice it occasionally happens that a matrix will become wedgedfast on the bar or that it will assume an improper position thereon, sothat it becomes necessary to remove it. In order to permit access to thematrix and its disengagement from the bar and the feed-screws, it hasheretofore been necessary to mount one of the screws in swingingsupports, so that it can be swung backward bodily away from its positionand out of engagement with the matrix.

The object of the present invention is to provide for the release of thematrices Without the employment of the movable screw, which in certainclasses of machines is inadmissible.

To this end the invention consists, broadly, in mounting thedistributer-bar in such manner that it may be moved bodily away from itsoperative position in order to carry the matrices thereon away from thefeed-screws or equivalent feed devices. To this end the Specification ofLetters Patent. Application filed August 17, 1906. Serial No. 330,98:

Patented Nov. 27, 1906.

distributer-bar may be mounted in any suitable supports and combinedwith any suitable means for moving it to and from the operativeposition. In the accompanying drawings 1 have illustrated eccentrics forthis purpose, and their use under ordinary conditions is recommended;but it will be understood by the skilled mechanic that they may bereplaced by any other equivalent devices.

Figure 1 is a side elevation of a distributerbar mounted 1n accordancewith my invention. Fig. 2 is a vertical cross-section of the same on theline 2 2. Fig. 3 1s a top plan view.

Referring to the drawings, A represents the horizontal stationarydistributer bar, provided at its lower edge with a series of orizontaldistributer-teeth a.

B represents one of the matrices notched in its upper end to straddlethe lower edge of the bar and provided with teeth to engage those ofthe. bar. All matrices bearing a given character have a number orarrangement of teeth special thereto, and the teeth of the bar A are soarranged that the matrices, applied horizontally at one end andsupported by the interlocking teeth, will be sustained as they movealong the bar until they arrive at their respective points Where theyare to be discharged and delivered to the magazine. 7

O C O represent the three screws parallel with the distributer-bar insuch relation thereto as to engage the upper and the lower ends of thematrices, as shown, so that as the screws are rotated they will carrythe series of matrices along the bar to the points of delivery in theusual manner.

The foregoing parts may all be of the same construction as in the patentabove referred to. The barAinstead of being fixed immovably to theframe, as heretofore, is provided on the top near each end withhorizontallyslotted plates D, which embrace an eccentric E, carried by ahorizontal shaft F, seated in the main frame. The shafts F are providedwith crank-arms G, which are connected by a bar H, these connectionsserving to cause a simultaneous and corresponding movement of botheccentrics.

When the parts stand in the position shown by full lines in Fig. 1, thedistributer-bar A A is held firmly in operative position; By turning theeccentrics in the direction indicated by dotted lines thedistributer-bar may be lowered in relation to the screws 0 to suchextent as to disen age the ears of the pendent matrices from t efeed-screws. Being thus released, the matrices may be moved freely alongthe bar and readily disengaged therefrom. The rising motion of thedistributerbar may be limited by stop-screws I or equivalent stopdevices, against which it will be-firimly seated by the action of theeccentrics, which stand normally upon or slightly past the center.

For convenience in operating the parts a handle K may be connected toone of the cranks or other suitable operating connections may beemployed.

The essence of the invention lies in so mounting the bar A that it maybe readily' moved from the operative position in such manner as todisengage the matrices from the 3. In combination with the distributerp.bar A, and the adjacent feed-screws, means for moving the bar to efiectthe disengage ment of the suspended matrices, from the screws.

4. In combination with the distributerbar A and the adjacentfeed-screws, eccentrics arranged substantially as described, to effectthe vertical movement of the bar.

5. In a distributer of the class described, a

distributer-bar and supports adapted to permit instantaneous verticalmovement, of the bar from an operative to an inoperative position.

In testimony whereof I hereunto set my hand, this 13th day of August,1906, in the presence of two attesting witnesses.
